ATTACHMENT FOR PLovvs.

Specification of Letters Patent.

Application filed October-23,1918. Serial No. 259,402.

To all whom it may concern:

Be it known that I, ROBERT BRUCE NUN- NALLY, a citizen of the United States, residing at Mission, in the county of Hidalgo and State of Texas, have invented a new and useful Attachment for Plows, of which the following is a specification.

This invention relates to an attachment for plows, one of the objects being to provide a device which can be connected readily to the plow standard and does not require the use of a supplemental beam or handles. A still further object is to provide an attachment of this character which is inexpensive and can be applied to different makes of plows without requiring any particular skill.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the ad vantages of the invention as set forth in the appended claims.

In the accompanying drawings the pre ferred form of the invention has been shown.

In said drawings Fi ure 1 is a side elevation of a plow having the attachment applied thereto.

Fig. 2 is a plan view thereof.

Fig. 3 is an enlarged section on line 33. Fi 1.

Fig. 4 is a plan view of a portion of a sli htlv modified structure.

Referring to the figures by characters of reference, 1 designates a plow beam having handles 2, braces 8. and a standard 4. These parts can be of any well known make, proportions. and arrangement.

The attachment constituting the present invention includes a metal frame having its front portion 5 arranged so as to rest flat against the front of the standard 4, the frame being twisted at the ends of this front portion, as shown at 6 to provide rearwardly diverging portions 7 each of which has a longitudinal series of apertures 8. At the outer end of each of these portions 7 is another twist 9 from which a side portion 10 extends. These side portions are integral with the end portions of a cross bar 11 and braces 12 are bolted or otherwise fastened to the rear ends of the side portions 10 and extend upwardly and inwardly, there being a series of apertures 13 in the upper end portion of each brace 12. The bolts 14 employed for fastening the braces 3 to the bandles can also be utilized for fastening the braces 12 and by placing a clamping plate 15 back of the standard 4 and connecting it to the front portion 5 of the frame with a bolt 16, said frame can be anchored securely to the plow structure, as will be obvious.

The standards of the supplemental plows or cultivators have been shown at 17 and are extended over the bar 11 and under the diverging portions 7. Clamps 18 connect said standards to the bar 11 and bolts 19 connect the front ends of the standards to the portions 7. With this arrangement of parts the standards 17 can be adjusted relative to each other. It will be noted that the entire attachment can be connected readily to a plow and the necessary parts are reduced to the minimum number.

Instead of using the clamps 18 slots 19 can be formed in the rear portions of the horizontal portions of the standards 17 for the reception of bolts 20 extending through apertures 21 in the bar 11. A series of these apertures is provided and they allow for adjustment of the standards relative to each other. This modified arrangement has been shown in Fig. 4.

What is claimed is:-

1. An attachment for plows including a frame, a clamping plate attached to the front portion of the frame. said portion and plate being adapted to receive a plow standard therebetween, braces connected to the sides of the frame at the rear thereof and adapted to be adjustably connected to the handles of a plow. standards extending over the rear portion of the frame and under the front portions thereof, and means for adjustably connecting the standards to said portions.

2. The combination with a plow having a standard and handles, of an attachment including a frame having its front portion extending across the front of the standard, a clamping plate back of the standard, a connection between said portion and the plate for clamping the plate upon the standard Patented J an. 14, I
